Effect of EPA on lipid synthesis in hMGEC. (A) Cultured in DMEM/F12/EGF for 4 days, (B) Cultured in DMEM/F12/EGF with 20 μM EPA, (C) with 50 μ M EPA, and (D) with 50 μM EPA plus 10 μM T0070907 for 4 days. (E) Cultured in DMEM/F12/EGF for 6 days, (F) with 20 μM EPA, and (G) with 50 μM EPA. (H) Bar graph showing a significant increase of lipid synthesis in cells cultured in DMEM/F12/EGF with EPA in time and concentration dependent manners via PPARγ signaling (*: P < 0.05).
